Diving Caves

I have to deal a lot with the consequences as I mainly do advanced training and not everybody is ready to start it.

We all appreciate the wide-angle panoramic views of a cave, whether on social media or, even better, live. However, to experience the latter safely, you must focus on the details.

Take a look at this picture. See that open circle in the rock?
This is where a diver’s light cable hooked, causing him to get stuck just as his body had already passed through. His first instinct was to free himself by moving the arm holding the light. When that failed, he had to switch the light to his other hand, reach back, and manually clear the cable. The process took several seconds.
Luckily, this occurred in a quite open passage rather than a restriction; it was simply a corner we were turning where the rock jutted out.

When an entanglement like this happens, you must reassess your dive configuration and adjust. You can streamline the gear mid-dive, but address the problem for yourself and the team also afterward. The diver's immediate fix was to loop the excess light cable in his hand, but he got stuck two more times, proving that was not the best solution. During the post-dive debrief, I suggested a proper fix: tucking the excess light cord under the wing, which is standard practice in sidemount training.
Another option is going cordless. However, even with modern battery improvements making handheld lights incredibly powerful, a combined light head and battery remains too heavy for my preference. I still favor a remote canister on the harness, running a standard light cord. The key is ensuring that the cord is carefully routed to eliminate entanglement risks when diving sidemount caves.

What was one of your minor problems you had on a dive recently and how did you fix it?

Every once in a while I also get some short notice reservations and I am super happy with how everything worked out. All gear that I brought fit at the first try, we had excellent conditions in casa Cenote with zero current to start, dancing crabs, baby flounders, saw Pancho and slight flow when we returned. Second dive in cenote Tankah was full of turtles, awesome light, very cool orange clouds as some parts on the bottom, fish clouds at the cavern entrances and just overall stunning sea lilies. No diving pic though as I was guiding.
Very happy divers, very happy me

Why Old Gear Deserves a Second Life

In a world driven by disposable consumption, there's something quietly radical about choosing to rebuild rather than replace. When a piece of equipment breaks down, the instinct is to reach for a new one, shinier, faster, with a fresh warranty. But this reflex comes at a cost: environmental waste, unnecessary expense, and the loss of something that, with a little care, could serve just as well.

Rebuilding old appliances makes sense on almost every level. Financially as replacement parts cost a fraction of a new unit. Environmentally, you're keeping materials out of landfill and avoiding the energy-intensive manufacturing of a new product. Logistically, as shipments to Mexico take a long time and a lot of gear isn't available in local shops. And practically, older equipment was frequently built to a higher standard of repairability than today's sealed, glued-together devices ever are.

There's also another powerful logistical argument: local repair. Sending equipment back to a manufacturer means weeks of waiting, shipping costs, and the frustration of being without gear you depend on. A device that can be serviced locally stays in service. That accessibility matters, especially for specialized equipment where downtime isn't just inconvenient, it's a barrier to doing what you love.

Take my cave diving light. A rebuilt unit isn't a compromise, I got what I was asking for. The light head I love with the power of a newly built battery unit and charging options I can work with.

Rebuilding is slower than clicking "buy now." But for those willing to take that path, the reward is equipment that's better supported, longer-lived, customized and ready when I need it.

Let me know which gear you customized locally and how you like it
